|■ About Dissolved air flotation|
In settling process of wastewater treatment, water is purified by settling particles in wastewater. However, contaminants whose specific gravity is lower than water are made to be floated to water surface rather than settled down in order to be separated from water. However, contaminants whose specific gravity is lower than water are made to be floated to water surface rather than settled down in order to be separated from water.
Also, treatment method to float contaminants which have low specific gravity by pressurizing air is called dissolved air flotation. Tiny bubbles of air are generated in wastewater and they are mixed with wastewater containing contaminants with lower specific gravity than water. After the tiny bubbles catch and enclose the contaminants, they rise to surface using their buoyancy. In this way, contaminants are removed from wastewater.
Water in the sludge thickened in the sludge thickener tank are removed at dehydration process to a certain degree.
However, moisture content is normally more than 80% and the sludge still has adhesiveness and stickiness. Also, latter processes are not easy because of influence of flocculants. Our drying apparatus of KENKI DRYER with international patented technology can surely dry any sticky, adhesive and viscus sludge, and also materials in liquid state like slurry, without clogging inside of the dryer. Also, because of its simple structure, its price is low and apparatus cost of the dryer can be retrieved by reducing industrial waste disposal cost within 3 years. Dried materials can be recycled as fuel, bacterial fertilizer, soil conditioner, etc. since component of the material is hardly changed because of its low-temperature drying method.
It can be applied to a system with pyrolysis apparatus as well.
|Please consider KENKI DRYER for drying of sticky materials, adhesive materials and materials in liquid state that no other dryer can deal with.|
|Initial, running and maintenance costs are low because of its simple structure based on internationally patented technology.|
|For sludge drying, costs of our dryers are estimated to be retrieved within 2, 3 years by reducing industrial waste disposal cost.|
|For raw material slurry drying, laborious works of manual operation will be decreased significantly by replacing box shaped compartment tray dryer with our dryer|
|In case of organic wastes drying, the waste can be recycled as fuel, fertilizer, soil conditioner and feedstuff after being dried.|
